Let's divide 6872901 by 961
The aim is to understand the frequency of 961 in 6872901.

Step 1:
When dividing 6 by 961, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 961

Let's proceed to step 2:
The number 961 fits into 68 0 times, leaving a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 68 and we're left with 68.
Grab the next digit (7) from the dividend, add it to 68, then carry on: 687 / 961

Step 3:
When dividing 687 by 961, we get 0 with a remainder of 687.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 687 to get 687.
Fetch the next digit (2) from the dividend, attach it to 687 and continue: 6872 / 961

Step 4:
6872 divided by 961 is 7 with a remainder of 145.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 145 after subtracting 6727 from 6872.
Take the next digit (9) from the dividend and append it to 145, then repeat: 1459 / 961

Moving on to step 5:
961 can be fit into 1459 1 times, resulting in a remainder of 498.
Put 1 as the next digit of the answer. 
Result so far: 71.0
The remainder is 498 after subtracting 961 from 1459.
Append the next digit (0) from the dividend to 498 and continue with: 4980 / 961

Moving on to step 6:
If we divide 4980 by 961, we get 5 and a remainder of 175.
Write down 5 as next digit of the result. 
Result so far: 715.0
If we subtract 4805 from 4980, we get 175.
Grab the next digit (1) from the dividend, add it to 175, then carry on: 1751 / 961

Going ahead to step 7:
If we divide 1751 by 961, we get 1 and a remainder of 790.
Record the quotient 1 as the next digit in the result. 
Result so far: 7151.0
If we subtract 961 from 1751, we get 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7900, and continue the process.

Step 8:
961 can be fit into 7900 8 times, resulting in a remainder of 212.
Write down 8 as next digit of the result. 
Result so far: 7151.8
The remainder is 212 after subtracting 7688 from 7900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Moving on to step 9:
961 goes into 2120 2 times with a remainder of 198.
Use 2 as the next digit of our solution. 
Result so far: 7151.82
Subtract 1922 from 2120 to get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Moving on to step 10:
1980 divided by 961 is 2 with a remainder of 58.
Put 2 as the next digit of the answer. 
Result so far: 7151.822
Deduct 1922 from 1980 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Our division results in 7151.822 with a remaining 0.0058.
